Is there a RESTful API for the Ubuntu CVE Tracker (XML or JSON)? The HTML version is found at http://people.canonical.com/~ubuntu-security/cve/main.html.

The best API for CVEs I have found so far is at https://www.circl.lu/services/cve-search/. For example, if we want to use the API to get information about CVE-2016-7395, we run

curl http://cve.circl.lu/api/cve/CVE-2016-7395

which returns a JSON given by
